sion of the coin controlled mechanism, which modication is particularlyadaptable for domestic use.

Referring to the drawings more in detail, Ihave shown a cabinet I of anydesired type housing my 6 invention, the cabinet preferably having ashape and finish Yharmonizing with surroundings in which it is used. Thefront of the cabinet may be provided with a window 3 through which partsof the operating mechanism may be watched. A 10 colored lamp 2 ismounted in the cabinet above the operating mechanism, which lamp islighted throughout the operation of the mechanism for the purposes ofattracting attention and for providing suicient light to make theoperating 15 mechanism visible through the window 3.

As shown in Fig. 2 the mechanism comprising my improved phonograph anddriving motors therefor is supported on the shelf 4 xed in the upperportion of the cabinet I. In the lower part 20 of the cabinet isprovided an electrical amplifying unit 5 having a speaking unit 'I heldin place by suitable clips 6. A coin receiver 8 is also located at thebottom of the cabinet and is adapted to receive coins through the chute9 leading from 25 a suitable coin controlled mechanism housed within thebox II, said coin controlled mechanism preferably being of the typespecifically set forth in my application for patent, Serial No. 457,617,led on May 30, 1930.

As best shown in Figs. 3, 4 and 5, I provide a carrier I2 which consistsof a cross-head having arms I3 with cylindrical bores Il of such sizethat the guide rods I5 slidably t therein. The guide rods I5 arestationarily fixed at their ends 35 to the frame members I6 and I1 andthe crosshead or carrier reciprocates on the rods I5. The carrier I2 haslongitudinally extending record moving arms I8 and I9. The arm I 9 isprovided with an upwardly turned end 2| which is adapted 40 to engage arecord 23 on the turntable 22 when the record carrier is shifted towardthe right as viewed in Fig. fi, and the arm I 8 is provided with a bellcrank member 24 best shown in Fig. 8, normally held in the positionillustrated, by means of 45 a coil spring 25 for engaging and shifting arecord as the carrier is moved in the opposite direction. For thepurpose of shifting the carrier longitudinally of the guide rods I5, Ihave provided a mechanism comprising a relatively large horizontallypositioned gear 26 actuated by a pinion 21 driven by an electric motor28 which operates periodically, as will be more fully explainedhereinafter. 'I'he gear 26 is rotatably mounted on a stationarycross-bracket 29 and is provided with an arm 66 pin 56 by a set screwThe inner end of 3| fixed thereto by screws. The outer end 32 of the arm3| is pivoted by a set screw 33 to connecting rod 34 which -extendsbeneath the cross-'head I2 and is pivoted to the depending pin 36thereon so that when the gear 26 is rotated by the pinion 21, theconnecting rod 34 will reciprocate the cross-head I2 on the guide rodsI5.

A longitudinally extending .shift bar 31 is mounted at one end on thebracket 29 and at the other end on the frame member I1 by set screws 38and 39 which pass through slots 4| and 42 respectively in the bar 31 topermit longitudinal sliding movement of the bar. The: gear 26 isprovided with a depending lug 43 (Figs. 9 and 10) which is adapted toengage an inwardly bent arm 44 fixed on the inner side of the bar 31 forthe purpose of shifting the bar toward the left as the gear 26 rotatesin a clockwise direction as viewed from above. The cross-head I2 isprovided with a depending arm 46 which extends over the bar 31 and isadapted to engage an outwardly extending lug 41 on the bar 31 forshifting the bar to the right when the crosshead I2 is shifted to theright. The depending arm 46 is alsol adapted to engage a lug 5| on theswitch blade 52 for separating the contacts 53 and 54 when thecross-head is moved toward the left to its extreme position. Anvupwardly extending lug 65 on the bar 31-engages with the ratchet arm 55which is secured to and for rotary .movement with the lower portion ofthe tone arm pivot 51 as shown in Fig. 5. The pivot pin 56 is providedwith ahead 58 resting on the upper edge of the frame portion l|1 forsupporting the pin 56 in position. The upper end of the pin 56 ishingedly fixed to the tone arm 59 of the reproducer 6| #by a hinge pin62. The reproducer 6| may be of any suitable type which includes aneedle or the like 63 adapted to engage the record 23 for reproducingthe same. the arm 55 is provided with a pawl 66 which when moved to theright, as viewed in Fig. 9, rides upon the ratchet 61 engaging the teeth68 thereof. As it moves to the right the extension 69 on the upper endthereof engages a stationary upwardly bent arm 1| on the sliding block8| causing the lower portion to press downwardly on the ratchet 61, andbecause the ratchet is pivoted at 12, this downward force on one endcauses the hook 13 to be gradually lifted from its engagement with thespring catch 14 on the upper end of the switch blade 15 which is pivoted-at 16. The catch 13 is normally urged downwardly by coil spring 11. Theswitch blades 52 and 15 are yieldingly urged toward each other by a coilspring 18 and the blade 15 is yie'ldingly urged toward the right by aweaker spring v19.

Adjacent the left end of thebar 31, as viewed in Figj, is provided arecess 82 in the upperV edge thereof into which is seated a lift pin 83having its upper end engaging a bearing plate 84 on the tone arm 59lsuch that as the tone arm oscillates above the record being reproducedthe plate 84 always remains on the upper end of the pin 83.

By this arrangement it is possible to lift the reproducer from therecord at any point in its travel by lifting the pin 83 slightlyfromthe'position shown inFig. 6. To accomplish this lifting action, therecess 82 is provided with sloping cam ends 85 such that when the bar3,1 is shifted longitudinally in either direction out of the positionshown'in Fig. 6, the pin 83 is caused to ride upwardly over one of thecam surfaces-85 and ride upon the upper surface of the'bar 31, thusliftingthe reproducer'from the record or above the plane normallyoccupied by the record while .being reproduced. When the lug 65 movesaway from the ratchet arm 55,'the leaf spring 86 fixed to the frame I1by screws 81 moves the tone arm 59 a slight amount such that thereproducer will 5 engage in the marginal groove of the record 23 uponlowering of the tone arm. The tone arm is preferably provided with anelectric cable 88 which may lead to the amplifying unit 5 in the lowerpart of the cabinet. 10

Referring to Figs. 4 and 8, I have illustrated means for lifting therecord from its position on the turntable and depositing it in therecord supporting compartment. A vertically'movable pin 9| normallyurged to its lowermost position as illustrated in full lines in Fig. 8,by means of a. spring 92, is adapted to engage beneath the margin ofarecord 23 and lift the same into the position shown in broken lines.The pin 93| is moved to its raised position by a cam arm 93 fixed on theconnecting rod 34 such that when the connecting rod-is moved beneath thepin 9| the cam arm 93 causes the pin 9|l to lift the record. While therecord 23 is in the position shown in Fig. 8, the arm 2| on the left endof the crosshead I2 engages the left edge of the record and forces ittoward the right, causing it to ride upwardly over the cam 94 on thecross-member 95 forming one side of the record holding compartment. Thebell crank arm 24 being pivoted and normally urged to the position shownin Fig. 8, is adaptedto pass beneath a stack of records in the recordsupporting compartment consisting of the cross-member 95 and theconfining band 96, and after passing beneath the stack of records itnormally assumes its uppermost position and the forward edge 91 engagesbehind the low'- v ermost record in the compartment and uponsubsequently moving toward the left it moves the lowermost record withit, depositing the same' upon the turntable 22 in the position shown inFig. 4. The record supporting compartment is provided with an inwardlyextending tongue 98 which is adapted to engage the record 23 as. itpasses from the turntable to the compartment 45 for guiding the recordinto position. The record compartment is preferably supported at theright end by a bracket 99I secured to the frame member I6.

For the purpose of driving the turntable I have provided a motor |0|having a friction wheel |02 on'the upper end of itsfarmature shaft,which wheel is normally urged toward the turntable by a coil spring |03xed at one end to the motor bracket |04 which is pivoted at |05 and xedat the other end to an upwardly extending arm |06 secured by screws |01to the shelf 4.

Referring to Figs. 13 and 14 I have illustrated a wiring diagram showingthe main power line |08 connected into the coin controlled mechanism II. The conductor |09 passes from the coin controlled mechanism to themotor |0| and to the amplifying unit 5. The cable |09 also extends tothe contact member 54. The contact member 53 is connected by a conductorto the motor 28 which drives the gear 26 through the medium' of thepinion 21. The conductor ||0 also extends from the coin controlledlmechanism to the motors 28 and |0| and to the amplifying unit 5. For thepurpose of short circuiting the switch mechanism comprising contacts 53.and 54 I have provided a manually operable switch comprising contacts||2 and ||3 which are respectively lconnected to cables |09 and I |.v

In the wiring diagramillustrated in Fig. 14 75 In the operation of myinventionas herein illustrated and described, beginning with themechanism in the position illustrated in Fig. 4 with a record 23 on theturntable 22 and with the reproducer engaging the record, the motor |0|is driving the turntable so that the reproducer gradually moves towardthe center, carrying with it the inner end of the tone arm together withthe ratchet arm attached tothe lower end of the tone arm pivot 56. Whenthe pawl 66 on the ratchet arm 55 moves to the right a suflicientdistancethat the record has been fully reproduced, the ratchet 61 isforced downwardly and the hook 13 is lifted against the action of thespring 11, permitting the switch blade l 15 to move in a clockwisedirection by the force of the spring 18, thus closing thecontacts 53 and54, which completes the circuit through the motor 28. .The motor 28immediately starts and causes the gear wheel 26 to rotate, whichreciprocates the cross-head |2,to the right and at the beginning of thismovement the cam arm 93 lifts the inner edge of the record so that itslides upwardly over the cam 94 by reason of force eX- erted on theopposite edge of the record by the upturned arm 2|. Also at thebeginning of this motion the lug 43 on the gear wheel 26 shifts the bar31 to the left, which through the medium of the lug 65 rotates the'reproducer to the left sumciently that it is in position for beginningthe reproduction of another record.

Prior to any appreciable movement of the reproducer, the cam face 85lifts the pin 83, which in turn wlifts the tone arm for raising thereproducer from the record, so that as it is swung to the left about thepivot pin 56 it does not scrape across the face of the record.

When the cross-head or carrier moves toward the right, the depending arm4'6 leaves contact with the pin 5| on the switch blade 52, permittingtheswitch blade to oscillate under the force of springs 18 and 19 tosuch a position that the hook 13 will engage over the upper end 14 onthe switch blade 15, thus preparing the switch to be again opened by thearm-46 when it again engages the pin 5|. Subsequently and while thecarrier is still moving toward the right, the depending arm 46 contactsthe lug 41 on the horizontal bar 31 and forces it toward the right.

As the record passes into the compartment which is adapted to support astack of records, the tongue 93 guides the record into position on thetop of the stack. The bell crank arm 24 passes beneath the stack ofrecords and engages the further edge of the lowermost record, and uponcontinuation of movement of the gear 26 the cross-head together with theturntable mounted thereon is caused to move to the left.

As the cross-head oscillate's toward the left, carrying with it a recordfrom the bottom of the stack by the aid of the bell crank arm 24, theturntable makes contact with the friction wheel on the armature shaft ofthe motor |0'| which it left when it moved toward the right, and beginsrotation for the reproduction of the record then on the turntable, Asthe cross-head approaches the limit of its movement toward the left, thearm 46 engages the pin 5|, breaking the circuit between the contacts 53and 54, thus stopping the shifting motor 28. Just prior tothe stoppingof the motor 28, the lug 43 on the gear 26 engages the arm 44 on the bar31 and moves the bar 31 a slight distance to the left sumcient,

however, to permit the pin 83 to drop into the' recesses 82, thuslowering the reproducing needle 63 onto the margin of the record,whereupon the new record in position is reproduced and the cycle ofoperation is continuously repeated unless the circuitis broken.

When it is desirable to use my invention in public places where it isintended that the patrons shall pay for the music, the coin controlledmechanism may be employed for breaking the circuit at some intimatepoint in the cycle of operation.

In Figs. 3, 11, 12 and 13 I have shown an adap-' tationof the coincontrolled mechanism to my inventions By the arrangement illustrated thelug 43 on the gear wheel 26 engages an arm |20 extending from the coincontrolled mechanism, when the lgis in such a. position that the record,having been reproduced, has been moved to position on the stack ofrecords. As the lug 43 passes over the arm |20, it is rst pressed to the.position shown in Fig. 1'1 in broken lines and it then snaps back tovertic'al position as shown in full lines, by which movement the circuitis broken and is reestablished only by the insertion of a coin in thecoin slot |2| on the front of the cabinet, which coin passes through themechanism and is deposited in the coin box 8 after passing through theconduit 9 from the mechanism to the box 8. This coin controlledmechanism is not a part of this invention and is therefore not describedin detail but it constitutes the invention of my applicationhereinbefore referred to.

If for any reason it is desired to remove a record from the turntablewithout first having it reproduced or at any time during thereproduction of the record prior to its completion, the switchcomprising contacts ||2 and ||3 may be closed, which forms a shuntacross the contacts 53 and 54 and begins the cycle of operation the sameas though the record had been completed and the contacts 53 and 54 hadbeen closed in the manner vpreviously described.

It will be apparent to those skilled in the art that modifications maybemade in the form of my invention, disclosed in the accompanyingdrawings and herein described, without departing from the principle .ofmy invention, and I desire to avail myself of such changes andmodications as come within the scope of the appended claims.
